Nike Grind is a collection of recycled materials developed by Nike that is composed of pre-consumer manufacturing scraps, recycled post-consumer shoes from the Reuse-A-Shoe program, and unsellable footwear. The purpose of Nike Grind is to eliminate waste and close the loop on Nike's product lifecycle. The materials are used to make various Nike products, athletic surfaces and products for other companies. Materials recycled include rubber, foam, fiber, leather and textile blends, which are separated and ground into a wide range of granules.
